About this course

The Official CompTIA Network+ Instructor and Student Guides (Exam N10-008) have been developed by CompTIA for the CompTIA Network+ candidate. Rigorously evaluated to validate coverage of the CompTIA Network+ (N10-008) exam objectives, The Official CompTIA Network+ Instructor and Student Guides teach the knowledge and skills to deploy, secure, and troubleshoot SOHO and enterprise networks, and to prepare candidates to take the CompTIA Network+ certification exam.

New Features

  • Easily Implemented in Classroom Environments

The content and resources have been reworked to make them more flexible to suit a variety of classroom formats, whether there are 5 days or 16 weeks to teach the material, or something in between.

  • Lengthy on-premises Lab Activities that require organizations to setup and maintain equipment have been removed from the eBook. Instead, graded labs (CertMaster Labs) are available hosted on the Learn on Demand Systems platform. These modular labs require only a modern browser and internet connection, saving organizations hours of setup time. Their short durations of 10-30 minutes allow for labs to be more easily integrated in coursework. As a result, instructors will no longer see the setup guide in the Instructor Resources.
  • Reworked Presentation Tools: The PowerPoint lecture slides have been enhanced with support notes. In addition, the presentation planner has multiple formats depending on the course duration and includes information on labs, topics and performance-based questions to make it easier for instructors to plan lectures and use classroom time effectively.
  • Rigorously Evaluated to Ensure Adequate Coverage of Exam Objectives

CompTIA employs trusted third-party subject matter experts to review the content against the exam objectives and validate that an appropriate breadth and depth of coverage has been achieved. This process helps ensure that students using The Official CompTIA Network+ Guides are adequately prepared for the CompTIA Network+ certification exam. Additionally, icons at the beginning of each topic call out the specific exam objectives covered.

  • Alignment and Consistency Across Book, Labs, and Assessment

The book, labs, and assessment all work together with a similar approach and voice ensuring that instructors and students have a cohesive “single-sourced” solution for their Network+ courses. The presentation of course topics is supplemented with regular opportunities for hands-on labs, which are delivered via CertMaster Labs. Each lesson has exam-style multiple choice assessments, available via the CompTIA Learning Center. There is also a final assessment synthesizing concepts from all lessons.

Engaging Video Program

Videos embedded within the lessons complement the instructional content by presenting real-world networking scenarios from experts’ experience, and by demonstrating key concepts and tasks in the course.

  • Robust Assessment

Practice questions for each lesson and a final assessment covering all Lessons, more than 300 questions in total, are available in the CompTIA Learning Center to help students practice and demonstrate what they have learned.


The CompTIA Network+ certification exam will verify the successful candidate has the skills required to implement enterprise-level wired and wireless network solutions; identify and troubleshoot network performance issues; and harden networks against threats to mitigate security vulnerabilities.

The major areas of emphasis include:

  • IP addressing and connecting networks
  • Wireless standards and technologies
  • Network availability
  • Securing and hardening networks

The Network+ exam covers five major domains:• Networking Fundamentals (24%)

  • Network Implementations (19%)
  • Network Operations (16%)
  • Network Security (19%)
  • Network Troubleshooting (22%)
